Definition at line 86 of file bits/alloc_traits.h.

template<typename _Alloc>
typedef _Alloc::value_type std::allocator_traits< _Alloc >::value_type

Member Function Documentation

template<typename _Alloc>
static pointer std::allocator_traits< _Alloc >::allocate ( _Alloc &  __a,
size_type  __n 
) [inline, static]

Allocate memory.

Parameters:
__aAn allocator.
__nThe number of objects to allocate space for.

Calls a.allocate(n)

Definition at line 300 of file bits/alloc_traits.h.

template<typename _Alloc>
static pointer std::allocator_traits< _Alloc >::allocate ( _Alloc &  __a,
size_type  __n,
const_void_pointer  __hint 
) [inline, static]

Allocate memory.

Parameters:
__aAn allocator.
__nThe number of objects to allocate space for.
__hintAid to locality.
Returns:
Memory of suitable size and alignment for n objects of type value_type

Returns a.allocate(n, hint) if that expression is well-formed, otherwise returns a.allocate(n)

Definition at line 315 of file bits/alloc_traits.h.

template<typename _Alloc>
template<typename _Tp , typename... _Args>
static auto std::allocator_traits< _Alloc >::construct ( _Alloc &  __a,
_Tp *  __p,
_Args &&...  __args 
) [static]

Construct an object of type _Tp.

Parameters:
__aAn allocator.
__pPointer to memory of suitable size and alignment for Tp
__argsConstructor arguments.

Calls __a.construct(__p, std::forward<Args>(__args)...) if that expression is well-formed, otherwise uses placement-new to construct an object of type _Tp at location __p from the arguments __args...

template<typename _Alloc>
static void std::allocator_traits< _Alloc >::deallocate ( _Alloc &  __a,
pointer  __p,
size_type  __n 
) [inline, static]

Deallocate memory.

Parameters:
__aAn allocator.
__pPointer to the memory to deallocate.
__nThe number of objects space was allocated for.

Calls a.deallocate(p, n)

Definition at line 327 of file bits/alloc_traits.h.

template<typename _Alloc>
template<typename _Tp >
static void std::allocator_traits< _Alloc >::destroy ( _Alloc &  __a,
_Tp *  __p 
) [inline, static]

Destroy an object of type _Tp.

Parameters:
__aAn allocator.
__pPointer to the object to destroy

Calls __a.destroy(__p) if that expression is well-formed, otherwise calls __p->~_Tp()

Definition at line 355 of file bits/alloc_traits.h.

template<typename _Alloc>
static size_type std::allocator_traits< _Alloc >::max_size ( const _Alloc &  __a) [inline, static]

The maximum supported allocation size.

Parameters:
__aAn allocator.
Returns:
__a.max_size() or numeric_limits<size_type>::max()

Returns __a.max_size() if that expression is well-formed, otherwise returns numeric_limits<size_type>::max()

Definition at line 366 of file bits/alloc_traits.h.

Referenced by std::forward_list< _Tp, _Alloc >::max_size(), and std::list< __inp, __rebind_inp >::max_size().

template<typename _Alloc>
static _Alloc std::allocator_traits< _Alloc >::select_on_container_copy_construction ( const _Alloc &  __rhs) [inline, static]

Obtain an allocator to use when copying a container.

Parameters:
__rhsAn allocator.
Returns:
__rhs.select_on_container_copy_construction() or __rhs

Returns __rhs.select_on_container_copy_construction() if that expression is well-formed, otherwise returns __rhs
